Mineral composition variation in Boletales mushrooms—indication of soil properties and taxonomic influence

The efciency of element accumulation depends on numerous factors, where the physico-chemical characteristics of the
soil seem to be very important, and the role of taxonomic rank in the accumulation of elements by mushrooms seems to be
important. The aim of the study was to compare the mineral composition of 7 species belonging to Leccinum and Suillus
genera, collected between 2019 and 2021 from localizations in the west-central part of Poland. The research aimed to indicate
the role of selected soil parameters in stimulating/inhibiting the accumulation of elements by selected Boletales mushroom
species and to answer the question about the role of species belonging to the genus as an indicator determining the specifc
mineral composition of fruiting bodies. Soil pH and other soil properties (granulometric composition, organic carbon, degree
of organic matter decomposition) may signifcantly afect mushrooms' mineral composition. Mushroom species belonging to Leccinum genus exhibited the higher amount of essential major and trace elements than species of Suillus genus). It
suggests that the afliation of the studied mushroom species to a specifc genus may afect their mineral composition, and
the physicochemical properties of the soil may be responsible for the lack of a clear division in the efciency of element(s)
accumulation. Selected species contain high amounts of K, Cu, Fe, and Zn, while others, such as selected Suillus gravellei
fruiting bodies, also contain As and Cd. The results described serve as an introduction to a broader scientifc discussion and
require many further studies to confrm the role of taxonomic ranks and the infuence of soil characteristics on the accumulation of elements by fruiting bodies.
